Oh yes, all these masters do not like to read anything - this is duty and a lot of bukaf and read the manual when there is nothing to read or everything is already broken…. As for the fact that they do not bear any guarantee for their work, I was convinced personally. And the address, do not tell me where the box was repaired, otherwise I already broke my head who to turn to for repairing the torque converter. And about the plaintive groans, you filter it!

Spare parts came and I started assembling the automatic transmission. Spent garage quartzization for sterility, dressed white coat, latex surgical gloves

and started assembling. Replaced all gaskets, oil seals, friction and steel discs. After 3 hours, the automatic transmission was assembled and ready for installation. It remains to install it on the car and carry out sea trials. Hopefully another 100,000 km. will run.

Finally we got around to putting together a machine gun and writing a post. Filming is not very difficult. The main thing is to get to the bolt which is from the side of the distributor. Located in the very opera! To take the distributor to the side, you need to get the shaft that connects the box to the distributor! Stud for 8, and the principle of a reverse hammer. Collected the device from available tools. Internal filter clogged with trash! In general, see the photo!
I think everything is clear!

Oleg, in the first photo it seemed to me, or does the right drive oil seal need to be changed (the side at the oil seal is eaten)?

comments to photo 2,3,4:
in photo 2, it is adapted for pulling out the intermediate shaft from the left side of the automatic transmission (it comes out easily);
in photo 3 you can see that the hairpin went through the hole for the CV joint in the wheel and how far the shaft comes out of the automatic transmission;
in photo 4 the shaft itself, the splines at the ends are different, where there are simply splines in the automatic transmission, where the smooth surface of the automatic transmission gears (when installed, it comes into place by hand)

Yes, it seems normal))) maybe such a photo!

pay attention, he should have, as it were, a skirt made of elastic around all the circumferences, the photo seems to show that from this skirt only a piece of about 2.5 cm remained on the right in the center

Well, what is that)))) okay, these are trifles! The oil seal can cost $ 3-5. Let's change!

Oleg, in the first photo it seemed to me, or does the right drive oil seal need to be changed (the side at the oil seal is eaten)?

It sat down in place by hand.

yes, I forgot, repair only on hand with manuals from this box, there is a lot of useful things

Congratulations on the completion of the renovation!

I said thank you in my heart more than once. I can repeat it here.
Thanks a lot!

ATTENTION! This text does not carry any important information on automatic transmission repair, there are no diagrams, advice on what and how to do. There is a lot of sensible text, almost no specifics. You won't find anything particularly useful here. This is just the author's reasoning on the feasibility of repairing an automatic transmission with his own hands and his opinion on the approach to this matter.

AUTOMATIC TRANSMISSION F4A232 MITSUBISHI IS CONSIDERED. With other boxes, the situation may be completely different.
So.
After installing the contract automatic transmission, instead of the broken one, the previous box remains on the hands. Naturally dead.
ALL OPTIONS IMPLY THAT YOU HAVE A WORKING BOX ON YOUR CAR AND THERE IS A SECOND INOPERATIVE STATE, AVAILABILITY, THE ABSENCE OF WHICH IS NOT CRITICAL FOR YOU.

As always, there are several options:
1. Do nothing. There is a place where to put it in the garage, let it rust. Maybe later someday, for some reason it will come in handy.

2. Throw away, hand over for scrap. Well, everything is clear. Out of sight and out of sight, so to speak, maybe even 500 rubles will be given.

3.Submit for analysis. Here, how lucky, maybe someone needs it (they say it is quite scarce), or maybe no one will take it. And if they do, then most likely at the price of scrap metal.

4. Disassemble for spare parts for the installed box. It's not a bad option, you can save money in the future if the breakdown is not identical in both, they will turn out to be interchangeable and someone will take the bulkhead of two boxes at once to assemble one of them ... It is unlikely that you will be given a guarantee for such a repair, but they will definitely take money. And most likely the same as during a normal repair of such an automatic transmission

Do not be lazy to look under the car, it should be clean there. Red spots will indicate an oil leak from the transmission. Checking the oil level regularly is a must. Normally, it should be translucent, reddish in color. No burning smells or muddy shades! If they appear, it's time to change the oil.Automatic transmission malfunctions often arise due to improper operation. The transmission becomes unusable due to insufficient oil level or overheating. For this reason, the gears wear out, the machine can jerk when changing gears. As a result, any part of the automatic transmission may fail. Shocks while driving indicate overheating of the oil and the appearance of problems in the valve body.Aggressive driving with hard acceleration and braking will erase details. Does not add durability to the box and driving in traffic jams, slipping. All this leads to overheating of the box and has a bad effect on its general condition.All faults are divided into two subgroups. They can occur in

electronic control system,

mechanical and hydraulic parts of the gearbox.

If a malfunction occurs, the automatic transmission goes into emergency mode, that is, it goes into third speed and does not switch. The corresponding icon appears on the display.If problems have arisen with the electronics, then it will not be possible to fix them by repairing the automatic transmission. Therefore, it is important to understand the nature of the faults.In diagnostics, the main thing is to collect the necessary information and interpret it correctly. Therefore, it is better to consult a specialist.Determine what the problem is at the service station, and take care of the repair yourself. Without proper experience and equipment, you will spend a lot of time on diagnostics. There are mechanical and computer diagnostics.General scheme of diagnostic procedures:

check the oil,

check the operation of the engine at idle speed, the connection points of the wiring and cables,

determine the error codes of the operation of the control units (CU) of the gearbox and engine,

check the box on a car without movement,

check the automatic transmission in motion,

check the pressure inside the control system.

If the cause of the malfunctions is electronics problems, then most likely you will not need to dismantle and disassemble the automatic transmission. Diagnostics of malfunctions in this system is carried out by the control unit. It monitors the sensor signals, the transmission ratio and the resistance of the output circuits. Malfunctions of such parts and assemblies may occur:

input sensors,

electronic control unit,

executive devices of the control system,

violation of the integrity of the electrical wiring connections.

The transmission computer receives signals from various sensors. If some parameters are out of order, it writes the code of this problem (DTC) into memory. You can decrypt such numbers using a special scanner.These are the main problems of the automatic transmission itself. They are conventionally divided into three subgroups:

Damage to friction groups, bushings and housings, calipers, planetary gear sets, pump and other mechanics.

Defective transformer. This includes:

breaks in the splines of the wires,
mechanical destruction of the blades,
overrunning clutch,
wear of the main blocking clutch,
depressurization of the piston oil seal.
Problems with the mechanics of the hydraulic plate.

If the diagnostics were successful and you cannot do without dismantling, then we proceed to this stage of the automatic transmission repair.You will need a special lift, or at least a viewing hole. As well as a transmission jack and a set of keys. It is better to perform this procedure in a specially equipped garage or box. It will not be superfluous to invite several physically strong guys to help you move the removed box. Its weight is beyond the strength of even a very strong person. Further action plan:

disconnect all communication tubes and cables;

unscrew the torque converter mounting bolts, as well as the motor flywheel membranes;

remove and move the gearbox;

assess the scale of the breakdown and start repairing.

Before removing the gearbox, the oil does not need to be drained from it. However, then do not forget to substitute the container at the place where the oil supply pipes are attached when you disconnect them - otherwise you will get an ugly puddle under your feet.

All actions must be careful. Sudden movements can damage the splines on the input shaft of the diaphragm.

It is better to do automatic transmission repair with your own hands, having it at hand proprietary manual and a printed diagram of the gearbox. First you need to inspect all the systems that serve the gearbox, mounts and blocks. Then we proceed to the repair. For this:

We disassemble the gearbox, wash and dry the parts and check them for defects.
We change all gaskets, seals, as well as worn out parts.
Remove the inhibitor block and sump. We clean out the dirt inside. It looks like metal magnetic shavings.
We remove the wiring of the ring from the plug and push them inside the plug.
Remove the valve body, loosen the brake band bolts. We wash the valve body.
We check the clutches, gears and planetary gears for wear. We will replace it if there is such a need. All internal rubber bands must be changed!
We open the oil pump. We check all the details, especially the filter. We change what has already served its term. We use the manual so as not to swap parts.
We take out the valves and springs. We wash the valves. Their sticking can be the reason for incorrect operation of the automatic transmission. Replace the accumulator springs if they are broken.
Putting everything back into place. It is important not to confuse anything!
We replace rings and friction bolts.
We check the gear shift assembly and the large piston and put the oil pump in place.

Assembly takes place upside-down.

There are some points that it is advisable to take into account when repairing. Often a transmission problem is related to the filter. It will not be possible to change it without removing the valve body. And when it is removed, the gasket breaks. To replace it, you will need to disassemble the valve body completely. The same applies to the accumulator spring from first to second gear. A special stopper does not allow you to remove it without disassembling the valve body. All valve body gaskets are very similar, do not mix them up. Assembling the valve body, we tighten it with a torque wrench. It is important not to overtighten here.

If all the breakdowns are eliminated, we install the automatic transmission. The moment is responsible, haste is inappropriate here. During these works, the following recommendations should be adhered to:

When installing the automatic transmission in its place, the diaphragm is checked for end runout using an indicator head. If such a defect occurs, then it must be replaced.
The radiator is flushed until the gasoline is clean. Then a liter of transmission oil is poured into the gas turbine engine and put on the input shaft. You need to achieve a secure connection and a complete fit. Then you need to dock the engine with the box along the guide centering pins. The crankcases must abut completely.
Tightening the bolts in the box is the next step. After that, the absence of gaps along the entire plane is checked. After connecting all the highways, the correctness of the connections is checked.
At the final stage, oil is poured and the operation of the automatic transmission is checked at low engine speeds.

Beginning the installation of the box, be sure to check for the presence of centering pins on the crankcase flange - there should be two of them. If at least one is missing, the automatic transmission cannot be attached.

Automatic transmission repair and diagnostics do it yourself - not an easy but feasible task. Choosing a car with an automatic transmission, novice motorists believe that repairing it at home is impossible. This is not true. But before deciding to carry out such important work at home, you need to weigh all your possibilities. Then you will not be in for unpleasant surprises during the renovation.

There is nothing super complicated in automatic transmission repair. It is worth trying to figure it out yourself if:1. Guaranteed there is no service that can definitely do it.
2. You can do everything with German pedantry when disassembling and assembling.
3. There is a clean and bright place for neat work with the automatic transmission.
4. The presence of a book with a description of the automatic transmission is required.
I would, for starters, take off the automatic transmission pan and see what is going on there from below. In this case, you do not lose anything (except for oil and gaskets), at the same time you will look at the filter and what is already in the pallet from the automatic transmission
Maybe this will be all.A good tool is imported torque wrenches, good heads that fit tightly on the bolts, a compressor with a moisture separator, a purge kit, I will adapt it for flushing parts with gasoline under pressure. No special tool is needed. A complete understanding of what part is needed for what (even before opening) is simply necessary, as well as the ability to correctly make a defect. It is unrealistic to repair the torque converter without the absence of a lathe and the ability to conduct a smooth, continuous weld without fistulas. Special literature can be found through the Internet Elsa, Mitchell and others.Hands reached the box. It took 10-12 hours from the second call to the bulkhead, everything is familiar, everything is at hand. The first one did not work, tk. missing a couple of tools, as well as two freaks in the repair kit.Again I took it apart to a bolt, washed the case with chemistry to a shine:The freaks went through the soaking procedure again, the inside was abundantly oiled with oil, the clearances were checked according to the manual, the gaskets were all fresh, they were broached only with torque wrenches. In general, everything is as the doctor ordered.I know that it is strictly forbidden to assemble an automatic machine on sealant, therefore I did it very carefully and in a minimum amount.It is not yet known exactly when to put it. So the korobas is mothballed and waiting in the wings 🙂Take a newcomer to Drom.ru))).Took up the repair of the automatic transmission FN4A-EL (4F27E) from a friend on Premasi. I will post the report along the way here:.Tips and tricks from experts are welcome 🙂as far as I understand - the man-handles are labor. we do need e. join in! Respect and respect. You grabbed repairs, not even with our masya, but I look at your experience even from other people's cars more than we do. We are very glad to welcome you in our ranks.As far as I understand, if the symptoms are no 4 gears, then slowly we get sick to L in boxing.We order a lid and 4 elastic bands (sort of like) and for a start we only change the lid.Do I understand correctly that the cover can be removed without lowering the engine on the jack? On the chapel (there at the bottom of the link) this is done. And we have?And since this is the case, can you tell me the numbers of the cover and its oil seals (and the number?)?Just in case, the body number is CP8W-404953. 2002 year. 1.8 l.I think to order, since such is the case. At the next oil change in the box, I will ask you to replace it.Added by: I've found an estimate. What is desirable to change from this? As I understand it, the cover with rubber bands on it, as well as the clutches of 3-4 gears. Indicate point by point. Thanks!Wait kolupalis on existential.So, the catalog offers 4 covers, depending on the month-year. For 2002, two covers are offered depending on the month. How to define more precisely? 🙂With the oil seals on the cover, I realized:
FN11-19-762 (or -212 last digits) - 2 pcs., These are small oil seals;
FN01-19-655 - 2 pcs. - large oil seals.Karbofos Thanks! Found my cover)))Question to the topstarter. 2005 car. The mileage is small, apparently, that's why the lid is in order.And what could cause the wear of the rubber bands of the pistons?I also read a few links that are already well-known here.If your box kicks back, and it happened quite recently, open it, look at the lid and change the rings FN01-19-655 (2 pcs). These are the ones that sit on the lid and are larger in diameter. We order the cover itself as needed (if there is wear under the rings or the edges of the cover axis).If the box kicks forward by 3-4 and it happened quite recently, similarly, but FN11-19-762 (or -212 last digits) - 2 pcs. These are small rings on the lid. Similar to the previous case - we order the cover itself as needed (if there is wear under the rings or the edges of the cover axis).If we ride for a long time with such malfunctions, you need to remove the packages, look at the clutches, “pistons” (I don’t know how to call them correctly) and the brake band.Attention, question (again :-).

Let's take a look at the main features of Misubishi automatic transmissions.

All of the following applies ONLY to hydromechanical automatic transmissions and has nothing to do with variators!

Let's start with the nuances. Many off-road vehicles of the Pajero and Delica families are equipped with automatic transmissions from Toyota. And, therefore, the problems with these units seem to be at the wrong address. Again, the Toyota concern has such a huge annual production of cars that it seems to have to learn how to make “automatic machines”, like everything else. Therefore, when discussing automatic transmissions, we, first of all, will have in mind sedans, "automatic" machines for which are developed in "Mitsubishi" itself.

It is impossible to say that these are bad “automata”. The Japanese, as the experience of all our auto repair shows, in general, rarely do anything bad. But there are subtleties in their operation.

The first is that the level of fluid (or oil, which is not entirely accurate) in an automatic transmission is measured only in the "N" selector position. If you do this in the "P" position, which is allowed by the manuals for boxes from other companies, the level will be overestimated. There, inside this "automaton", at the "P" position, a small fountain "beats", due to which this increased level is obtained.

The second feature of Mitsubishi “automatic machines” is the presence of a one-time replaceable filter in it.Almost like a Mercedes. This, in turn, eliminates all sorts of "express replacements" of dextron in five minutes. True, this "express - replacement" can, under certain conditions, have a very negative effect on the box of any company. On Mitsubishi cars, changing the fluid also means changing the filter, and for this, you yourself understand, you need to dismantle at least the “machine” sump. Good or bad is hard to say. Probably good after all. At least most modern automatic transmissions of various companies (including, as already mentioned, Mercedes) also have a replaceable filter. Well, for our man, of course, it would be better to have a reusable filter. He took it off, washed the mesh in kerosene and can be reinstalled. There is no need to spend money on a new filter.

Owners of "Mitsubishi", if they are going to comply with the requirements of Japanese operating manuals, will have to buy a new filter when changing the fluid in the "machine". One consolation is that if the company provides for the replacement of dextron in 15 - 20 thousand, then the filter after 30 thousand kilometers, which is not very burdensome.

The third peculiarity of Mitsubishi automatic transmissions is that their "lockups" are destroyed quite often and for no apparent reason. "Lock up" is such a thing that locks the fluid coupling on the commands of the control unit. In order, so to speak, to increase the efficiency of the automatic transmission. After blocking the hydraulic coupling, the engine and the transmission are directly connected, and there are no longer any losses for heating the fluid in the fluid coupling. When this destruction occurs, you may not notice anything in the behavior of the machine. But the lining material of this "lockup" is sprinkled, clogging not only the filter, but also the cooling radiator of the automatic transmission and its control valves. And only then it causes various malfunctions in the box itself. Very observant drivers may notice that the shifts have become "smeared". Then, most likely, the fourth gear will disappear. Which, however, can disappear by itself.

This is the fourth feature of Mitsubishi machines. True, this defect is repaired quite quickly and even without removing the entire box. But you still have to fork out for new disks. Well, for a book on installing these disks. If your box has collapsed ("sprinkled") "lockup", then you cannot avoid serious repairs in a specialized auto workshop. Although often the owners prefer not to repair their failed automatic transmission, but to buy another, used one. This is usually much cheaper.

Well, and, perhaps, the last thing that the specialists of the Tekhnokhim firm, with whom we consulted, note. This is the so-called "rainy path" effect. It consists in the fact that when driving intensively on wet or slippery asphalt, when the wheels alternately hit either a dry area or a slippery one, the "ears" of the brake belts break off in the automatic transmission. And the 2nd and 4th gears disappear in the car.

In general, all the masters noted that the automatic transmissions of Mitsubishi are more demanding on the quality of the liquid (oil) poured into them. If an ordinary Toyota will manage without any problems ATF from Shell or Mobil, then Mitsubishi boxes require Mitsubishi SP3 recommended by ATF. Well, or "TransmaxZ" by "Castrol". Which is very expensive (a liter for about $ 15-20). This feature is caused by the fact that Mitsubishi gearboxes are more thermally loaded, which leads to dilution of conventional ATFs and they no longer properly lubricate the bearings.

So gentlemen, lucky ones, owners of various Mitsubishi, please drive more carefully. Your machines will be more intact.

Mitsubishi automatic transmission repair takes place in several stages:

Initial consultation by phones +7 (495) 795-16-69, +7 (903) 001-30-99
Computer diagnostics of Mitsubishi
Test Drive
Lift diagnostics
Dismantling of the Mitsubishi checkpoint. Troubleshooting of the box (may occur in your presence).
After agreeing with you the amount of repair and the terms of the guarantee, the checkpoint is repaired.

We repair Mitsubishi automatic transmissions of the entire model range: repair of automatic transmission Mitsubishi Pajero, Montero, Outlander, Galant, Lancer, Colt, Diamant, Eclipse, Mirage, etc.

When repairing the transmission - free evacuation of the car.

The warranty for the repair of the Mitsubishi automatic gearbox is from six months to 2 years!

Mitsubishi Montero Sport 2003 Having driven about 20 km by car, or when outside the air temperature from 5 degrees Celsius, the distributor spontaneously turns on to the 4H position, or rather when turning the wheels, it is felt that the distributor is turned on, drove it onto a lift, turn the wheels, the front end is turned on, hanging for about 40 minutes, it cools down automatic transmission and razdatka, the front end is disabled. What could be, what is the reason, the transfer case lever is in the AWD position all the time.

Answer: According to your description, presumably, the reason lies in the sensors on the transfer case. Such problems cannot be solved remotely; it is necessary to do at least computer diagnostics.

Mitsubishi Lancer 10 2008 The variator needs repair. What is the price of the issue?

Answer: The complex of work on the repair of the variator (removal / installation, disassembly / collection, troubleshooting) is 14,000 rubles. To this cost will be added the spare parts that will be required to restore the variator to working condition.

Determine the Mitsubishi box model:

Repair of a box automatic machine Mitsubishi Pajero at the Service Station is:

Car service speed
Guaranteed quality transmission restoration
Selection of only high-quality spare parts for automatic transmission Mitsubishi Pajero

During the work, the gearbox diagram of the Mitsubishi being repaired is taken into account, attention is paid to the "weak" places in the gearbox device of each car. We take only qualified specialists who have been educated and trained on modern equipment. A fairly wide range of transmission brands we deal with allows even young specialists of our company to gain the experience necessary to perform complex repairs. We dare to note that restoring automatic boxes is a painstaking work that requires patience. And it is the very specificity of the work that is the guarantee of quality - in the field of aggregate repair, only the work of conscientious specialists pays off.

The cost of repairing boxes for Mitsubishi Pajero is fixed; the price of automatic transmission spare parts is indicated in the price list, which we provide upon request. We work seven days a week and accept cars even in the most deplorable condition.

You can sign up for a Technical Service Station by calling our phone number, which is common for all divisions. 8 (495) 637-82-39. Be sure to call! We will advise you on all your questions.

Deciding what is required replacement of automatic transmission Mitsubishi Pajero, is accepted if it is cheaper to replace the box than to restore it. For example, you will need to reinstall more than half of the box's components.

Buy automatic transmission Mitsubishi Pajero you can through us. It will be several times cheaper to choose a used gearbox for Mitsubishi. However, it is impossible to guarantee that Mitsubishi Pajero with such a transmission will work for a long time.

We place an emphasis on new contract units, we offer options only after thorough tests for proper operation and, of course, without a guarantee. And even in this case, we still focus on remanufactured units, that is, removed, checked and received from a reputable supplier. The warranty only applies to contract units.

Please note that the information provided below is for informational purposes only.We will try to outline for you the main points in our approach to repairing Mitsubishi automatic transmissions, namely the box of a specific car model - Mitsubishi Pajero.

The automatic transmission can be repaired in most cases. The exception is situations when, for example, the gearbox of a car burned out (in this case, it is necessary to replace the unit). You need to understand that there are parts that can be replaced, and if the elements cannot be restored. Perhaps this is the basis on which to rely when calculating the cost of repair measures.

In addition to replacing parts, welding is characteristic of automatic transmission repair. So, you will need to work with argon if the gearbox housing is cracked or during the repair of the torque converter.

We offer the following complexes of repair and restoration work:
